Portability

The smartphone that you carry has far more capabilities than early computers that were the size of a house.

The credit goes to a series of developments from transistors to micropretzels and plastics that updated glass tubes and other bulky components! Electronics is the best example of how items became portable, however the portable cooler means much more to me.

According to 1 source, a farmer named Thomas Moore invented the ice box in 1772. It was an oval tub made from cedar wood and lined with rabbit fur. When someone invented styrofoam in 1944, the age of the portable cooler followed. The 1990s saw portable coolers on wheels and by the 2010s the two of us had solar-powered coolers and coolers that were integrated with items appreciate blenders and Bluetooth speakers. Heating, Ventilation, and A/C has yet to obtain tplot portability. The “H” and “V” are no problems because a campfire on the beach with a pleasant breeze serves as both a furnace and a cooking appliance for hot-pets and s’mores, but portable units that cool by evaporation or by blowing air over ice do exist, however these are not absolutely AC units. A tplot AC still needs bulky coils and a compressor unit, so they have lagged in becoming absolutely portable. Tplot portable AC units still need to be vented to the outside and drained of water that has condensed from the cooled air. They are a unbelievable solution for a room in your house lacking AC and they are portable to a degree in that they can be put in a vehicle and taken to another location. I anxiously await a portable AC component that I can take to the beach to join myself and others and our styrofoam cooler full of beer.
